50 000 000 000 Mark Amt Hattingen-Land

Hattingen-Land was one of hundreds of German district administrations forced into emergency currency printing during the hyperinflation peak of late 1923, when the Reichsmark's collapse made denominations that would have seemed absurd a year earlier not just necessary but already obsolete by the time notes left the press. The Amtskasse — essentially the district cashier's office — was not a bank and had no business issuing currency, but the breakdown of centralized monetary supply left local authorities with no alternative.

J.H. Born in Elberfeld was a regional commercial printer, not a specialist in banknote production. At this scale of output and denomination, security features were beside the point.
